1. A method for adjusting display brightness of a screen, for a terminal provided with an under-screen image capturing device, the method comprising:
detecting first display brightness within a first display region and detecting second display brightness within a second display region when a display screen of the terminal is displaying an image, the first display region being a region where the under-screen image capturing device is located and the second display region being a remaining region of the display screen of the terminal other than the first display region; and
determining grayscale brightness within the first display region when the display screen is displaying the image and adjusting grayscale brightness within the first display region based on the first display brightness and the second display brightness to allow adjusted grayscale brightness within the first display region to be consistent with grayscale brightness within the second display region;
wherein adjusting the grayscale brightness within the first display region comprises:
detecting third display brightness within the first display region and detecting fourth display brightness within the second display region based on grayscale brightness of content displayed on the display screen of the terminal being zero;
determining a difference between the first display brightness and the third display brightness as a first reflected light intensity within the first display region and determining a difference between the second display brightness and the fourth display brightness as a second reflected light intensity within the second display region;
determining a brightness difference between the first display region and the second display region based on the first reflected light intensity and the second reflected light intensity; and
adjusting the grayscale brightness within the first display region based on the brightness difference.
